CN8 Connects to the electromagnetic subassembly of distributor. Parts from left to right are,
1 Connects to freezer door switch.. Measurement of this point and null line gives the
operation voltage (DC 220V) of freezer lighting;
2-4 is spare.
5-6 Connect to the defrost heater. Measurement of these two point gives the resistance
(194±10Ω)of the defrost sensor and the operating voltage (AC 220V).
CN10 parts from left to right are
1 is spare.
2 Connects to live line of the compressor.
3 is spare.
4 Connects to water valve of icemaker. Measurement of this point and null line gives the
operating voltage (AC 220V) of the water valve.
5 is spare.
6 is null line
.
CN11 parts from left to right are,
1 Connects to L of the power filter board.
2-4 Connects to fridge door switch.. Measurement of this point and null line gives the
operation voltage (DC 220V) of fridge lighting;
3 Connects to N of the power filter board.
CN12 is the power supply for the power filter board. Parts from up to right are,
1-2 Connect to ground line.
3-4 supply DC 12V voltage.
5-6 supply DC 16V voltage.
CN13 Connects to the live line of power cable.
CN14 Connects to the null line of power cable.
3. Air Escaper Controlling Pinciple
(1)Air escaper’s open and close is controlled by fridge sensor R SNR.
(2)Air escaper is closed from the start of defrosting cycle to 15 minutes before the end of
defrosting cycle.
(3)Air escaper is closed firstly and then opened once, then open or close of air escaper is
controlled according condition (1).
(4)If air escaper is closed more than an hour, it will be opened at a time. Then open or close of air
escaper is controlled according fridge sensor R SNR.
(5)The heater of air escaper is controlled along with compressor.( The heater of air escaper is
connected when the compressor is running, and disconnected when compressor is shut. )
(6)When the air escaper is open (or close ) in 10 minutes, if the temperature is still rising (or fall),
the air escaper will open (or close) once more.
